The senator and presidential hopeful went to bat for dirty prosecutors, opposed marijuana legalization, and championed policies that endanger sex workers.

As she begins her 2020 presidential campaign, Sen. Kamala Harris is trying to position herself as a reformer who tirelessly works to correct the abuses of the criminal justice system. But the California Democrat has one big problem: her long record as a law-and-order prosecutor.

Harris's new memoir, The Truths We Hold, makes no mention of her past as an old-school drug warrior, a defender of dirty prosecutors, and a political opportunist who made life more dangerous for sex workers. Harris doesn't apologize for her previous stances, even those she now disavows; instead, she's decided to try to convince voters that she's always been a progressive prosecutor.

Here are some parts of her record that Harris is hoping you'll forget in the run-up to 2020.

HARRIS ON SEX WORKERS

Harris's political rise has been propelled by a yearslong, high-profile campaign against alleged sex traffickers. What she's actually done is help throw women in jail for having consensual sex, while trampling on the rule of law to advance her own political ambitions.

Harris fought to destroy Backpage.com, a classified ads site that sex workers used to find and screen clients, even though she publicly admitted that the site's founders, Michael Lacey and James Larkin, were protected from prosecution under federal free speech laws. But a month before Election Day in her Senate race, Harris went ahead and had them arrested anyway, parading them before cameras on pimping charges, which were then promptly dismissed by a judge.

When Harris got to Congress, she kept up her crusade, becoming a big proponent of the 2018 law known as SESTA-FOSTA. The result was that many sex workers no choice but to return to the streets, where soliciting clients is considerably more dangerous.

In her memoir, Harris decries America's "deep and dark history" of "people using the power of the prosecutor as an instrument of injustice," by framing innocent men or hiding exculpatory evidence. But during her time as California's top cop, she contributed to that history by repeatedly going to bat for dirty prosecutors.

Her office appealed the dismissal of a case in which a prosecutor had fabricated a confession to secure a conviction and fought an appeal in a case where the prosecutor lied to a jury during trial. In 2015, Harris tried to stop the removal of the Orange County District Attorney's office from a murder trial after it repeatedly failed to turn over evidence to the defense.

Her office even tried to keep a man in jail who had been wrongfully incarcerated for 13 years—even after a judge ruled he had proven himself innocent—because the man hadn't delivered the proof fast enough.

And as San Francisco District Attorney, Harris hid known misconduct by a crime lab technician who admitted to deliberately tainting evidence. The debacle has since led to the dismissal of hundreds of criminal cases.

HARRIS ON THE WAR ON DRUGS

Harris is a former drug warrior who is now refashioning herself as pro-legalization. That's a positive shift—but not a reason to rewrite the past or ignore the patterns it reveals in her judgment. For years after the cultural tide had turned in support of criminal justice reforms, Harris continued to support lock-'em-up policies that disproportionately hurt minorities.

In her new book, Harris reveals that her drug warrior mentality hasn't changed; it's just that her emphasis has shifted. Now she's hoping to funnel even more funds to law enforcement to "cut off the supply of fentanyl from China," and to "reinstate the DEA's authority to go after the major pharmaceutical manufacturers and distributors."

HARRIS ON MASS INCARCERATION

Harris is now an outspoken critic of America's system of mass incarceration, but she's worked hard over the years to lock more people up, for longer. And once these people were in prison, Harris saw to it that they'd have a hell of a time getting out.

Before her recent about-face, Harris chose not to endorse proposed sentencing reforms on the California ballot in 2012 and 2014, and she defended the constitutionality of cash bail until 2016.

Harris's office also fought an order to reduce California prison populations after the Supreme Court determined the conditions amounted to cruel and unusual punishment. Though she later claimed to be "shocked" at what they had done, Harris's attorneys argued that non-violent offenders should stay behind bars because the state needed the cheap labor they provide.

As she blazes her path to the White House in 2020, Kamala Harris is trying to rewrite her last chapter. But her record remains as a testament to her instincts and priorities when given real opportunities for change.
